Air conditioning has become everyone's favorite again in this season. Many people like to stay in the air-conditioned room in summer and enjoy the cool. In fact, staying in the air-conditioned room for a long time has many hazards. Let's take a look.
How many degrees of electricity do you need to turn on the air conditioner for one night
It depends on the input power of the machine and the difference between the set temperature and the ambient temperature. Theoretically, 1 degree = 1000 W / h, for example, if the input power of 1 HP machine (on the nameplate of the internal machine) is 850 W, the power consumption per hour is 0.85 degrees. Because the air conditioner has the function of automatic temperature control, the compressor does not always start. If the shutdown and start-up time are 1:1, the actual power consumption is about 0.43 degrees / h, and then multiply by the use time.
How much is the monthly electricity charge for air conditioning
1p = 0.735kw, 1 kwh = 1kwh (KWH) = 1kW * 1H, the maximum power of 1p air conditioner is 0.735kw, that is to say, the cooling power of air conditioner, the maximum wind power, the power consumption is 0.735 degrees per hour, 15 hours, 11.025, a month, then multiply by 30 days.
The disadvantages of staying in a room for a long time:
1、 The respiratory tract is the most vulnerable under the air conditioner. Once the air conditioner breaks through the vulnerable 'defense line' of the respiratory tract, the symptoms of cough, sneeze, runny nose and other colds will appear, that is, the upper respiratory tract disease. The air conditioner causes the more serious lower respiratory tract disease, which is pneumonia. Especially when working and studying under the central air conditioning, the central air conditioning is very suitable for Legionella transmission. The incubation period is about 2-12 days. If not treated in time, it will continue to have fever, dry cough, shiver, and even die of respiratory failure. In addition, although the room is cool, but the humidity is too low, which is not good for people 's eyes, nose mucosa. At the same time, the dust and dust mites in the room cannot circulate, and people with allergic constitution are also prone to allergic reactions.
2、 In addition to cold, air conditioning is also very harmful to the brain. Negative ions in the air can inhibit the central nervous system and relieve brain fatigue. However, the air conditioner absorbs too many negative ions, which makes more and more positive ions in the room. The imbalance of positive and negative ions also makes people's brain nervous system disorder and imbalance.
3、 In summer, the air temperature outside the room is high, the clothes are generally few, and the air conditioning and air conditioning blow badly. Such low temperature will stimulate the sharp contraction of blood vessels, resulting in joint damage, cold and pain, such as neck and back stiffness, waist and limbs pain, hands and feet cold and numb, etc. It is not surprising that many people pull and vomit when they are too cold in the room, which may lead to the weakening of gastrointestinal movement. In addition, they often eat cold drinks in summer and are controlled by cold inside and outside their intestines.
